Turf War - Capture a Tactical Spawn Point 
Capture a Tactical Spawn Point for the first time
Tactical Spawn Points can only be captured while playing as the Tactician. On screen, they will be displayed as icons like this and appear as spotlights as shown below. To capture a Spawn Point, simply stand/crouch within its radius until the bar on-screen turns completely green. Some Spawn Points will provide you with access to Jet Packs and Exos on certain maps.

Pilot's Wings - Mid-air kill 
Got a mid-air kill using the Jet Pack in any multiplayer mode
You must play on the Turbine Concourse SE-6 map in Warzone game mode in order to acquire this trophy. Jet Packs are located on each side of the map for both the ISA and Helghast and at Tactical Spawn Areas. You’ll find them folded up inside of what looks like a rack. Approach the equipment and press the
button to grab it. To activate it, press and hold
.
Press
to launch yourself into the air. While airborne you can press the
button to dash forward. This is especially useful to avoid enemy fire or to try and reach ledges/platforms otherwise out of your reach. Pressing
fires your machine gun. Take care not to fire it for too long or you’ll overheat your weapon thus leaving you vulnerable. You must be airborne (ie; not touching the ground) in order for the kill to count.

Iron Man - Get a kill with the Exo
Killed a player using the Exo in any multiplayer mode
The Exo is found only on the Corinth Highway map in Warzone game mode. There are 2 of these, 1 on each faction’s base for the ISA and Helghast. This devastating piece of equipment is very lethal, particularly in the hands of a skilled player. The armor can hold up to a modest amount of abuse and the weapons (Machine Gun & Rocket Launcher) are extremely accurate. Again,
is for the Machinegun, and
are the Rocket Launchers. Although the Exo provides you with some decent protection, be aware that you can still be killed very quickly by headshots and explosives
